Organic Lawn Feed

The two key windows are spring and autumn. Feed from mid-spring once the grass is actively growing to green it up and thicken it through summer, then again in early autumn to strengthen roots before winter. Use a spring or summer feed while growth is strong, and switch to an autumn feed once the season turns. Ease off feeding altogether once growth slows in late autumn.

An autumn feed that is lower in nitrogen and higher in potassium, which toughens roots and hardens grass off for winter rather than forcing soft top growth that frost can damage. Worm-cast feeds like our Lawn Boost are ideal because they release nutrients slowly and gently, feeding both the grass and the soil life beneath it.

It is best to wait. Feeding a heat-stressed, dry lawn can scorch it, and the grass cannot take the nutrients up properly when it is drought-dormant and the soil is parched. Hold off until the weather cools and the rain returns, then water the feed in if needed. Gentle organic feeds carry far less scorch risk than strong synthetic ones, but the timing still matters.

Yes, and it brings extra benefits. Organic worm-cast feeds release their nutrients slowly, so you get steady, even growth rather than a quick flush followed by a slump, and they feed the soil life that keeps a lawn healthy in the long term. They are also far gentler, with no scorch risk, and safe to use around children, pets and wildlife.

Strong synthetic feeds can scorch if they are over-applied or used in the wrong conditions, leaving yellow or brown streaks. Worm-cast feeds like our Lawn Boost are non-scorching because they release nutrients slowly and gently, so you can use them even on stressed or patchy grass without making things worse.

Both do the same job, it comes down to how you like to apply it. Granules are easy to spread by hand and release slowly for a long-lasting feed, which suits a main spring or autumn feed. A liquid feed acts faster and is great for a quick green-up or a boost between granular feeds. Many gardeners use granules as the base and top up with liquid through the season.
